The products of Fiber Reinforced Plastics (FRP) is light weight,
high strength,and can protect against climate and corrosion. It
has become a very important material and been extensively
applied in aerospace,vehicles,industry parts and exercise
equipments. The traditional manufacturing of FRP is by hand lay-
up which is high cost,long working time and economic
inefficient.A new process is by injection molding,in which
fiber mat is preplaced in a closed mold and the resin is then
pumped into the mold. This kind of promising manufacture
process is called Resin Transfer Molding (RTM). In this study,
experimental work is carried out to find out the influence of
each variable in RTM process.A simple rectangular mold,random
fiber mat with vacuum assistance and central gating is used.
The mold preheat temperature and injection pressure are taken
as the control parameters to fabricate the products. The
products are tested by MTS system to analyze its mechanical
properties. Influence of process variables on the properties of
the products is thus deeply investigated.
