Various possibilities?are?hidden in raw materials.It?makes?the development of new technologies always face?continuous challenges. We are?working?to?find new?materials that can develop?FRP?further.Combined with countless advantages of FRP,the materials can be applied in more fields?in real life. For example, first, the SMC material which can meet the mass production?demand is?introduced into the large-scale press molding industry, even extended TMC material from YMC material (kind of SMC material developed by Yashiro). Also, Yashiro explore and develop the RIM moulding with DCPD material and autocrave moulding with carbon prepreg. Depending on Yashiro's rich experience and reality project, not just a composites company, Yashiro is creating new technology and leading the era.

Yashiro's Design Divisio

From quotation to delivery, Yashiro is able to complete the total process independently. Satisfy with customer's QCD request and needs.

What is FRP?

FRP is Fiber Reinforced Plastics, a kind of composites material which use fiberglass to enhance plastic and increase its strength.

FRP's feature include ageing resistance, fire resistance, corrosion resistance, heat insulation, light weight and high strength.
Except glass,carbon,silicon carbideal,aramid and metal so can be treated as reinforced fiber. And resin includes unsaturated polyester resin, epoxy resin and phenolic resin.

FRP can be applied to residential assembly (bathtub, purifying tank etc.), railroad assembly (unit toilet, waste tank etc.), automobile assembly (diffuser, body etc.), healthcare assembly (CT / MRI etc.), environmental assembly (wind power generation cover etc.), from this, it can be seen that FRP already being extensive used around the world.

GFRP glass fiber reinforced plastics

A strong composite material created by laminating glass fiber with unsaturated polyester resin.

  • Rolling Stock front masks
  • Rolling Stock waste tanks
  • Rolling Stock lavatory units, etc.
CFRP carbon fiber reinforced plastics

The composite material (prepreg etc.) that made of carbon fiber and epoxy resin become familiar beforehand was baked with autoclave device of high temperature and high pressure.

  • Rolling Stock   front coupler covers etc.
  • Motor Vehicles  diffusers etc. 
DCPD gdicyclopentadiene

Shock resistance material formulated by RIM forming method, contains thermosetting resin.

  • Medical Equipment CT covers etc.
